Abstract
An overview of the National Institute of Standards and Technology (NIST) high temperature blackbodies, both in operation and in development, suitable for heat flux sensor calibration is presented. Typical results of calibrations using the transfer technique in the 25-mm Variable Temperature Blackbody (VTBB) are presented to demonstrate the long-term repeatability of the calibrations of a Gardon gage in a spherical blackbody with cooled enclosure for gage housing was conducted. Results of this study demonstrated the influence of convection associated with absolute calibration of sensors in a cooled-enclosure. Plans for further development of the transfer technique to higher heat flux levels and the associated technical issues are discussed.Citation
